T he main purpose of this article is to analyze exchange rate behavior based on monetary fundamentals in the context of Iranian economy over the period 1990:2 to 2014:3. To do so, two monetary exchange rate models is investigated, the first by regarding interest rate differential as a monetary variable, and the second one regardless of interest rate differential as a monetary variabl...

in recent years, iran has experienced high level depreciation of the nominal exchange rate (ner). the ultimate effects of such depreciation on iranian families’ welfare and income distribution have been a challenging issue among policymakers and researchers. accordingly, this study evaluates the economic effects of ner depreciation on the rice market, using spatial price equilibrium model. the ...

abstract this study uses gravity model to examine the most important determinants of was agricultural trade. to this aim, import and export statistics of iran agricultural products for the period 1380 to 1387 was provided from iran customs organization and other information was obtained from different internet bases. random effects estimating and hausman test ratio result in fixed effects model...

due to the limitations of the “life table method” the exponential model was used to estimate the iud termination and retention rate among 1,390 women. since the conditional probability of iud termination during the first month of insertion is considerably higher than the subsequent months, data relating to the first 30 days was considered separately. furthermore a constant termination rate was ...

A new simple analytical model for prediction of cooling rate in the solidification process based on the local heat flux density extracted during solidification is introduced. In the modeling procedure, a solidifying control volume is considered in the mushy zone in which a heat balance equation is used to derive the present model. As the local heat flux density is a measurable parameter, the pr...

background: governance is one of the main functions of health research system (hrs) that consist of four essential elements such as setting up evaluation system. the goal of this study was to introduce a new web based research evaluation model in iran. methods: based on main elements of governance, research indicators have been clarified and with cooperation of technical team, appropriate softw...

this paper represents a new region-based active contour model that can be used to segment images with intensity non-uniformity and high level noise. the main idea of our proposed method is to use gaussian distributions with different means and variances with incorporation of intensity non-uniformity model for image segmentation. in order to integrate the spatial information between neighboring ...

The Moving Picture Experts Group (MPEG) video-based point cloud compression (V-PCC) standard encodes a dynamic by first converting it into one geometry video and color then using coder to compress the two sequences. We propose analytical models for distortion bitrate of V-PCC reference software, where models’ variables are quantization step sizes used in encoding videos. Unlike previous work, o...

We describe the 2017 version of Microsoft’s conversational speech recognition system, in which we update our 2016 system with recent developments in neural-network-based acoustic and language modeling to further advance the state of the art on the Switchboard speech recognition task. The system adds a CNN-BLSTM acoustic model to the set of model architectures we combined previously, and include...

The aim of our research is to provide a unified model for the composition and management of consumer care services. We identify design, composition, distribution and management as key stages of this model and propose an Intelligent Collaborative Care Management (ICCM) System as its realisation. The distribution and management stages are implemented as multi-agent systems. Agents in the distribu...
